rsync of iSCSI

does the iSCSI target have to exist on the remote ReadyNAS2100 or will it be created automagically

The backup manager will back up the iSCSI disk image, so it is essentially a single large file backup.

I can select the local iSCSI target in step 1 of the backup.. that makes sense. however, in step 2, it seems "remote: Rsync Server" is the correct choice, and it seems the host should be the IP Address or hostname of the remote ReadyNAS. So, what is the PATH set to, and where do LOGIN and PASSWORD get defined? Are they setup on the remote ReadyNAS in Security - Users and Groups?

Path should contain the name of the target share or rsync module. On the ReadyNAS, rsync logins and passwords are configured in the rsync access tab of that share. This is because rsync uses its own password system and does not integrate into the standard authentication mechanisms.

What about the option for SSH? If I use that, do I not enter anything into the LOGIN and PASSWORD fields?

Over SSH, we only allow keys.

How Do I get the public key installed on the remote server?

The option is in the rsync tab for the share.

Is there any benefit to enabling "compression"?

Probably not.

and finally, can the backup of an iSCSI target actually do incrementals, or will it always backup the entire target?

It's going over rsync, so it should just be doing incrementals.
